Conformance

+ +

+The SGI OpenGL conformance tests verify correct operation of OpenGL +implementations. I, Brian Paul, have been given a copy of the tests +for testing Mesa. The tests are not publically available. +

+

+This file has the latest results of testing Mesa with the OpenGL 1.2 +conformance tests. Testing with the preliminary OpenGL 1.3 tests has +also been done. Mesa passes all the 1.3 tests. +

+

+The tests were run using the software X11 device driver on 24-bpp +and 16-bpp displays. +

+

+Mesa 4.0 and later pass all conformance tests at all path levels. +Note that this says nothing about the conformance of hardware drivers +based upon Mesa. +

+ + +
+
+COVERAGE TESTS
+--------------
+
+Test that all API functions accept the legal parameters and reject
+illegal parameters.  The result of each test is either pass or fail.

CVS Branch Information

+ +

+The Mesa3d sources are split up into two branches. A branch that is to +remain as stable as possible, and an unstable branch where development +work for new versions will be done. The current stable branch is +tagged mesa_3_4_branch while the unstable branch is just +the default. The goal is to adopt and even/odd stable/unstable +versioning scheme similar to the Linux kernel. Hence releases of Mesa +3.2.X should be more stable than Mesa 3.3.X.

All versions of +Mesa after 3.0 will also be tagged with a branch id. Mesa 3.1 has the +tag mesa_3_1, Mesa 3.2 will be mesa_3_2, +Mesa 3.3 mesa_3_3, etc..

+ +

+To checkout a specific branch of mesa just pass -r and +the branch tag after your cvs command. For example cvs checkout +-r mesa_3_4_branch Mesa will checkout the 3.4 branch and +cvs update -r mesa_3_4_branch will convert your current +branch to the 3.4 dev branch. +Consult http://www.durak.org/cvswebsites/doc/cvs_5.php3#SEC54 +for more on branching in cvs. +

+ +

+To see a list of all the CVS branchs run cvs log README (or any +other file) and look for the section labeled symbolic names. +You'll see something like this: +

Debugging Tips

+ +

+ Normally Mesa (and OpenGL) records but does not notify the user of + errors. It is up to the application to call + glGetError to check for errors. Mesa supports an + environment variable, MESA_DEBUG, to help with debugging. If + MESA_DEBUG is defined, a message will be printed to stdout whenever + an error occurs. +

+ +

+ More extensive error checking is done when Mesa is compiled with the + DEBUG symbol defined. You'll have to edit the Make-config file and + add -DDEBUG to the CFLAGS line for your system configuration. You may + also want to replace any optimization flags with the -g flag so you can + use your debugger. After you've edited Make-config type 'make clean' + before recompiling. +

+

+ In your debugger you can set a breakpoint in _mesa_error() to trap Mesa + errors. +

+

+ There is a display list printing/debugging facility. See the end of + src/dlist.c for details. +

Development Notes

+ + +

Adding Extentions

+ +

+To add a new GL extension to Mesa you have to do the following. +

+   If glext.h doesn't define the extension, edit include/GL/gl.h and add:
+	- new enum tokens
+	- new API function entry points
+	- #define GL_EXT_the_extension_name 1
+
+   If adding a new API function (call it glNewFunctionEXT):
+	- insert glNewFunctionEXT()into src/apiext.h
+	- edit src/types.h and add NewFunction to the gl_api_table struct
+	- implement gl_NewFunction() in the appropriate src file
+	- hook gl_NewFunction() into pointers.c
+	- add display list support in dlist.c for save_NewFunction()
+	- add glNewFunctionEXT to gl_GetProcAddress() in extensions.c or
+	  in the device driver's GetProcAddress() function if appropriate
+
+

+If adding new GL state be sure to update get.c and enable.c +

+

+In general, look for an extension similar to the new one that's already +implemented in Mesa and follow it by example. +

+ + + +

Coding Style

+ +

+Mesa's code style has changed over the years. Here's the latest. +

+ +

+Comment your code! It's extremely important that open-source code be +well documented. Also, strive to write clean, easily understandable code. +

+ +

+3-space indentation +

+ +

+If you use tabs, set them to 8 columns +

+ +

+Brace example: +

+
+	if (condition) {
+	   foo;
+	}
+	else {
+	   bar;
+	}
+
+ +

+Here's the GNU indent command which will best approximate my preferred style: +

+
+	indent -br -i3 -npcs infile.c -o outfile.c
+
+ + +

+Local variable name example: localVarName (no underscores) +

+ +

+Constants and macros are ALL_UPPERCASE, with _ between words +

+ +

+Global vars not allowed. +

+ +

+Function name examples: +

+
+	glFooBar()       - a public GL entry point (in dispatch.c)
+	_mesa_FooBar()   - the internal immediate mode function
+	save_FooBar()    - retained mode (display list) function in dlist.c
+	foo_bar()        - a static (private) function
+	_mesa_foo_bar()  - an internal non-static Mesa function

+ + + +

Making a New Mesa Release

+ +

+These are the instructions for making a new Mesa release. +

+ +

+Prerequisites (later versions may work): +

+ + +

+Be sure to do a "cvs update -d ." in the Mesa directory to +get all the latest files. +

+ +

+Update the version strings in src/get.c and src/X/fakeglx.c to return +the new Mesa version number. +

+ +

+Create/edit the docs/RELNOTES-X-Y file to document what's new in the release. +Edit the docs/VERSIONS file too. +Update the docs/IAFA-PACKAGE file. +

+ +

+Edit Make-config and change the MESA_MAJOR and/or MESA_MINOR versions. +

+ +

+Edit the GNU configure stuff to change versions numbers as needed: +Update the version string (second argument) in the line +"AM_INIT_AUTOMAKE(Mesa, 3.3)" in the configure.in file. +

+ +

+Remove the leading `dnl' from the line "dnl AM_MAINTAINER_MODE". +

+ +

+Verify the version numbers near the top of configure.in +

+ +

+Run "fixam -f" to disable automatic dependency tracking. +

+ +

+Run the bootstrap script to generate the configure script. +

+ +

+Edit Makefile.X11 and verify DIRECTORY is set correctly. The Mesa +sources must be in that directory (or there must be a symbolic link). +

+ +

+Edit Makefile.X11 and verify that LIB_NAME and DEMO_NAME are correct. +If it's a beta release, be sure the bump up the beta release number. +

+ +

+cp Makefile.X11 to Makefile so that the old-style Mesa makefiles +still work. ./configure will overwrite it if that's what the user runs. +

+ +

+Make a symbolic link from $(DIRECTORY) to Mesa. For example, +ln -s Mesa Mesa-3.3 This is needed in order to make a correct +tar file in the next step. +

+ +

+Make the distribution files. From inside the Mesa directory: +

+	make -f Makefile.X11 lib_tar
+	make -f Makefile.X11 demo_tar
+	make -f Makefile.X11 lib_zip
+	make -f Makefile.X11 demo_zip
+
+ +

+Copy the distribution files to a temporary directory, unpack them, +compile everything, and run some demos to be sure everything works. +

+ +

+Upload the *.tar.gz and *.zip files to ftp.mesa3d.org +

+ +

+Update the web site. CJ Beyer (cj@styx.phy.vanderbilt.edu) can +help with this and uploading to the ftp site. +

+ +

+Make the announcement to the SourceForge.net sites: mesa3d-dev@lists.sf.net, +mesa3d-users@lists.sf.net and mesa3d-announce@lists.sf.net +

+ + +

Autoconf info

+ +

+In order to run the bootstrap script you'll need: +

+

+autoconf 2.50
+automake 1.4-p5
+libtool 1.4

Downloading / Unpacking

+ +

+Mesa can be downloaded from the + +SourceForge download area. +

+ +

+Since version 2.3, Mesa is distributed in two pieces: main library code +and demos. If you're upgrading from a previous version of Mesa or you're not +interested in the demos you can just download the core Mesa archive file. +

+ +

+Mesa is available in at least three archive formats: +

+ +
+1. GNU zip/tar
+
+	Download MesaLib-X.Y.tar.gz and optionally MesaDemos-X.Y.tar.gz
+	Unpack with:
+		gzcat MesaLib-X.Y.tar.gz | tar xf -
+		gzcat MesaDemos-X.Y.tar.gz | tar xf -

+	or
+		tar zxf MesaLib-X.Y.tar.gz
+		tar zxf MesaDemos-X.Y.tar.gz
+
+	If you don't have gzcat try zcat instead.
+
+2. Unix compressed/tar
+
+	Download MesaLib-X.Y.tar.Z and optionally MesaDemos-X.Y.tar.Z

+After unpacking you'll have these directories (and more): +

+
+Makefile.X11	- "old" top-level Makefile for X11-based systems
+Make-config	- system configurations used by the Makefile.X11
+configure	- the GNU autoconf script

+
+
+ + + + +

1. High-level Questions and Answers

+ +

1.1 What is Mesa?

+

+Mesa is an open-source implementation of the OpenGL specification. +OpenGL is a high-level programming library for interactive 3D graphics. +See the OpenGL website for more +information. +

+

+Mesa 5.0.x supports the OpenGL 1.4 specification. +

+ + +

1.2 Does Mesa support/use graphics hardware?

+

+Yes. Specifically, Mesa serves as the OpenGL core for the XFree86/DRI +OpenGL drivers. See the DRI website for +more information. +

+

+There have been other hardware drivers for Mesa over the years (such as +the 3Dfx Glide/Voodoo driver, an old S3 driver, etc) but the DRI drivers +are the modern ones. +

+ +

1.3 What purpose does (software) Mesa serve today?

+

+Commercial, hardware-accelerated OpenGL implementations are available for +many operating systems today. +Still, Mesa serves at least these purposes: +

+ + +

1.4 How do I upgrade my DRI installation to use a new Mesa release?

+

+You don't! The Mesa source code lives inside the XFree86/DRI source tree +and gets compiled into the individual DRI driver modules. +If you try to install Mesa over an XFree86/DRI installation, you'll lose +hardware rendering (because Mesa's libGL.so is different than the XFree86 +libGL.so). +

+

+The DRI developers will incorporate the latest release of Mesa into the +DRI drivers when the time is right. +

+ +

1.5 Are there other open-source implementations of OpenGL?

+

+Yes, SGI's +OpenGL Sample Implemenation (SI) is available. +The SI was written during the time that OpenGL was originally designed. +Unfortunately, development of the SI has stagnated. +Mesa is much more up to date with modern features and extensions. +

+

+miniGL is a subset of OpenGL +for PalmOS devices. + +TinyGL is another +subset of OpenGL. +

+

+There may be others but Mesa is the most popular and feature-complete. +

+ +
+
+ + + +

2. Compilation and Installation Problems

+ + +

2.1 What's the easiest way to install Mesa?

+

+If you're using a Linux-based system, your distro CD most likely already +has Mesa packages (like RPM or DEB) which you can easily install. +

+ + +

2.2 Running configure; make Doesn't Work

+

+Unfortunately, the GNU autoconf/automake/libtool system doesn't seem to work +too well on non GNU/Linux systems, even after installing gmake, gcc, etc. +For that reason, Mesa's old-style makefile system is still included. +The old-style system uses good old traditional Makefiles. Try the following: +

  cd Mesa-x.y.z
+  cp Makefile.X11 Makefile
+  make
+
+You'll see a list of system configurations from which to choose. +For example: +
  make linux-x86
+
+

+If you're experienced with GNU autoconf/automake/libtool and think you can help +with maintence, contact the Mesa developers. +FYI, the Mesa developers generally don't use the autoconf/automake system. +We're especially annoyed with the fact that a +5000-line script (libtool) +is needed to make shared libraries (ugh). +

+ +

2.3 Mesa still doesn't compile

+

+If the old-style Makefile system doesn't work either, make sure you have +the most recent version of Mesa. +Otherwise, file a bug report or post to the Mesa3d-users mailing list. +Give as much info as possible when describing your problem. +

+ + +

2.4 I get undefined symbols such as bgnpolygon, v3f, etc...

+

+You're application is written in IRIS GL, not OpenGL. +IRIS GL was the predecessor to OpenGL and is a different thing (almost) +entirely. +Mesa's not the solution. +

+ + +

2.5 Where is the GLUT library?

+

+GLUT (OpenGL Utility Toolkit) is in the separate MesaDemos-x.y.z.tar.gz file. +If you don't already have GLUT installed, you should grab the MesaDemos +package and unpack it before compiling Mesa. +

+ + + +

2.6 What's the proper place for the libraries and headers?

+

+On Linux-based systems you'll want to follow the +Linux ABI +standard. +Basically you'll want the following: +

+ +

+After installing XFree86 and the DRI drivers, some of these files +may be symlinks into the /usr/X11R6/ tree. +

+

+The old-style Makefile system doesn't install the Mesa libraries; it's +up to you to copy them (and the headers) to the right place. +

+

+The GLUT header and library should go in the same directories. +

+
+
+ + + +

3. Runtime / Rendering Problems

+ +

3.1 Rendering is slow / why isn't my graphics hardware being used?

+

+Stand-alone Mesa (downloaded as MesaLib-x.y.z.tar.gz) doesn't have any +support for hardware acceleration (with the exception of the 3DFX Voodoo +driver). +

+

+What you really want is a DRI or NVIDIA (or another vendor's OpenGL) driver +for your particular hardware. +

+

+You can run the glxinfo program to learn about your OpenGL +library. +Look for the GL_VENDOR and GL_RENDERER values. +That will identify who's OpenGL library you're using and what sort of +hardware it has detected. +

+

+If your DRI-based driver isn't working, go to the +DRI website for trouble-shooting information. +

+ + +

3.2 I'm seeing errors in depth (Z) buffering. Why?

+

+Make sure the ratio of the far to near clipping planes isn't too great. +Look + +here for details. +

+

+Mesa uses a 16-bit depth buffer by default which is smaller and faster +to clear than a 32-bit buffer but not as accurate. +If you need a deeper you can modify the parameters to + glXChooseVisual in your code. +

+ + +

3.3 Why Isn't depth buffering working at all?

+

+Be sure you're requesting a depth buffered-visual. If you set the MESA_DEBUG +environment variable it will warn you about trying to enable depth testing +when you don't have a depth buffer. +

+

Specifically, make sure glutInitDisplayMode is being called +with GLUT_DEPTH or glXChooseVisual is being +called with a non-zero value for GLX_DEPTH_SIZE. +

+

This discussion applies to stencil buffers, accumulation buffers and +alpha channels too. +

+ + +

3.4 Why does glGetString() always return NULL?

+

+Be sure you have an active/current OpenGL rendering context before +calling glGetString. +

+ + +

3.5 GL_POINTS and GL_LINES don't touch the right pixels

+

+If you're trying to draw a filled region by using GL_POINTS or GL_LINES +and seeing holes or gaps it's because of a float-to-int rounding problem. +But this is not a bug. +See Appendix H of the OpenGL Programming Guide - "OpenGL Correctness Tips". +Basically, applying a translation of (0.375, 0.375, 0.0) to your coordinates +will fix the problem. +

+ +
+
+ + + +

4. Developer Questions

+ +

4.1 How can I contribute?

+

+First, join the Mesa3d-dev mailing list. That's where Mesa development +is discussed. +

+

+The +OpenGL Specification is the bible for OpenGL implemention work. +You should read it. +

+

Most of the Mesa development work involves implementing new OpenGL +extensions, writing hardware drivers (for the DRI), and code optimization. +

+ +

4.2 How do I write a new device driver?

+

+Unfortunately, writing a device driver isn't easy. +It requires detailed understanding of OpenGL, the Mesa code, and your +target hardware/operating system. +3D graphics are not simple. +

+

+The best way to get started is to use an existing driver as your starting +point. +For a software driver, the X11 and OSMesa drivers are good examples. +For a hardware driver, the Radeon and R200 DRI drivers are good examples. +

+

The DRI website has more information about writing hardware drivers. +The process isn't well document because the Mesa driver interface changes +over time, and we seldome have spare time for writing documentation. +That being said, many people have managed to figure out the process. +

+

+Joining the appropriate mailing lists and asking questions (and searching +the archives) is a good way to get information. +

Compilation and Installation for Unix/X11

+ +

+If you're not using a variant of Unix with X11, see the +Supported Systems and Drivers section +for instructions. +

+ +

+There are two methods for building Mesa on Unix/X11 systems: +

+ +
+
NEW-STYLE
+
+Basically, type "./configure" followed by "make" +This should work on most Unix-like operating systems. +Unfortunately, autoconf/automake seems to seldom work reliably on non-Linux +systems. For that reason, the old-style make system is still supported +(and is the preferred method of the Mesa developers). +
+
+
OLD-STYLE
+
+Simply type make and you'll see a list of supported +system configurations. Pick one and type make config. +More details below. +
+
+ +

+NOTE: The GLUT library and demonstrations programs are in the +MesaDemos-x.y.z.tar.gz file. If you don't have GLUT or you want to +run some demos, download the MesaDemos package too. +

+ +

+In either case, building Mesa entails the following: +

+

+ + + +

NEW-STYLE compilation and installation

+ +
+0) If you've downloaded Mesa via CVS there will not be a "configure"
+   script.  You'll have to run the "bootstrap" script first.  This script
+   may not work on any OS other than Linux.  You'll need these programs
+   to run the bootstrap script:
+
+	autoconf 2.50
+	automake 1.4-p2
+	libtool 1.4
+
+
+1) Run the configure script
+
+	./configure [options]
+
+For Linux, it is recommended that you use:
+	./configure --prefix=/usr
+So that the headers and libs are located according to the Linux/OpenGL
+standard spec at http://oss.sgi.com/projects/ogl-sample/ABI/
+
+Possible options are:
+
+--prefix=DIR
+	The toplevel directory of the hierachy in which Mesa
+	will be installed (DIR/include,DIR/lib etc.).
+	The default is "/usr/local".
+
+--sysconfdir=DIR
+	The directory where Mesa configuration files
+	will be stored.	The default is "$prefix/etc".
+	You may want to overwrite the default with --sysconfdir=/etc.
+
+--enable-static
+	Enable building of static libraries.
+	Static libraries are NOT built by default.
+	
+--disable-shared
+	Disable building of shared libraries.
+	Shared libraries are built by default.
+
+--with-pic
+--without-pic
+	In normal operation, libtool will build shared libraries from
+	PIC objects and static archives from non-PIC objects, except where one
+	or the other is not provided by the target host.  By specifying
+	--with-pic you are asking libtool to build static archives from
+	PIC objects, and similarly by specifying --without-pic you are asking
+	libtool to build shared	libraries from non-PIC objects.
+	libtool will only honour this flag where it will produce a
+	working library, otherwise it reverts to the default.
+	
+--enable-debug
+	Enable debugging messages (disabled by default).
+	
+--enable-profile
+	Enable profiling (disabled by default).
+	
+--disable-optimize
+	Disable extra optimizations (enabled by default,
+	i.e., optimize for maximum performance).
+	
+--enable-warn
+	Enable extended compiler warnings (disabled by default).
+	
+--enable-x86[=ARG]
+--disable-x86
+	Enable/disable x86 assembler support to speed up Mesa
+	(autodetected by default). You may set `on' or `off'.
+	
+--enable-3dnow[=ARG]
+--disable-3dnow
+	Enable/disable 3Dnow support to speed up Mesa
+	(autodetected by default). You may set `on' or `off'.
+	
+--enable-mmx[=ARG]
+--disable-mmx
+	Enable/disable MMX support to speed up Mesa
+	(autodetected by default). You may set `on' or `off'.
+	
+--enable-sse[=ARG]
+--disable-sse
+	Enable/disable SSE support to speed up Mesa
+	(autodetected by default). You may set `on' or `off'.
+	If you have a PentiumIII and want to use SSE make sure you have the
+	PIII Linux kernel-patch installed or things will fail!
+	You can get the patch from http://www.redhat.com/~dledford/linux_kernel.html
+	
+--with-glide[=DIR]
+--without-glide
+	Enable/disable support for Glide (disabled by default).
+	DIR is the installation directory of Glide.
+	If Glide cannot be found, the driver won't be built.
+	
+--with-glut[=DIR]
+--without-glut
+	Don't/use already-installed GLUT (autodetected by default).
+	DIR is the installation directory of Glut.
+	If GLUT cannot be found, the version shipped with Mesa will be built.
+	
+--with-ggi[=DIR]
+--without-ggi
+	Enable/disable support for GGI (autodetected by default).
+	DIR is the installation directory of GGI.
+	If GGI cannot be found, the driver won't be built.
+
+--disable-ggi-fbdev
+	Don't build the GGI fbdev target (autodetected by default).
+	
+--disable-ggi-genkgi
+	Don't build the GGI generic KGI driver (autodetected by default).
+	
+--disable-ggi-savage4
+	Don't build the GGI Savage4 KGI driver (autodetected by default).
+	
+--disable-osmesa
+	Disable OSmesa (offscreen rendering) support (enabled by default).
+
+--with-svga[=DIR]
+--without-svga
+	Enable/disable support for SVGALib (autodetected by default).
+	DIR is the installation directory of SVGALib.
+	If SVGALib cannot be found, the driver won't be built.
+
+--x-includes=DIR
+	Search for the X include files in DIR.
+	
+--x-libraries=DIR
+	Search for the X library files in DIR.
+
+User specific compiler options can be set using the shell variable
+CFLAGS. For instance,
+	CFLAGS="-g -O2" ./configure
+(on some systems: env CFLAGS="-g -O2" ./configure)
+sets the compiler flags to "-g -O2".
+
+For more options run "./configure --help" and read INSTALL.GNU.
+
+2) To build the Mesa libraries run:
+
+	make
+
+When finished, libGL.so will be in src/.libs/, libGLU.so will be in
+si-glu/.libs/, etc.
+
+Optionally, you can strip the libraries using
+
+	make strip
+	
+Now make sure that you have the permissions to install Mesa in the 
+specified directories, for example, by becoming super user ("su")
+Then run:
+
+	make install
+
+Mesa is now installed.
+Please don't move the installed files but rerun all installation
+steps if you want to use other directories.
+
+
+3) To test whether Mesa works properly you might want to run the Mesa demos:
+
+	make check
+	
+Builds all demos.
+
+	make exec
+
+Builds and executes all demos.	
+
+ + + +

OLD-STYLE compilation and installation

+ +

+This procedure usually works when ./configure ; make fails. +

+ +

+Note: If you tried ./configure ; make but it failed, +first copy the top-level Makefile.X11 file over +Makefile. +

+ +

+First, just type make alone. +You'll see a list of supported system configurations. +Choose one and type make config. +The Mesa libraries and demo programs will be compiled. +

+ +

Header and library files

+ +

+The standard location for the OpenGL header files on Unix-type systems is +in /usr/include/GL/. +The standard location for the libraries is /usr/lib/. +For more information see, the + +Linux/OpenGL ABI specification. +

+ +

+If you'd like Mesa to co-exist with another implementation of OpenGL that's +already installed, you'll have to choose different directories, like +/usr/local/include/GL/ and /usr/local/lib/. +

+ +

+To install the Mesa headers, do this: +

+	cp -r include/GL /usr/include
+
+ +

+To install the Mesa libraries, do this: +

+
+	cp -pd lib/* /usr/lib
+
+	(The -pd options preserve symbolic links)
+
+ +

LD_LIBRARY_PATH

+ +

+On Linux and similar operating systems the LD_LIBRARY_PATH +environment variable can be used to indicate a list of directories to +search for shared libraries. +If you don't install Mesa in /usr/lib/ you may have to +set the LD_LIBRARY_PATH variable in order to use the Mesa +libraries. +

Introduction

+ +

+Mesa is a 3-D graphics library with an API which is very similar to +that of OpenGL.* +To the extent that Mesa utilizes the OpenGL command syntax or state +machine, it is being used with authorization from Silicon Graphics, +Inc.(SGI). However, the author does not possess an OpenGL license +from SGI, and makes no claim that Mesa is in any way a compatible +replacement for OpenGL or associated with SGI. Those who want a +licensed implementation of OpenGL should contact a licensed +vendor. +

+ +

+Please do not refer to the library as MesaGL (for legal +reasons). It's just Mesa or The Mesa 3-D graphics +library.
+

+ +

+* OpenGL is a trademark of Silicon Graphics Incorporated. +

+ + +

Project History

+ +

+The Mesa project was founded by me, Brian Paul. Here's a short history +of the project. +

+ +

+August, 1993: I begin working on Mesa in my spare time. The project +has no name at that point. I was simply interested in writing a simple +3D graphics library that used the then-new OpenGL API. I was partially +inspired by the VOGL library which emulated a subset of IRIS GL. +I had been programming with IRIS GL since 1991. +

+ +

+November 1994: I contact SGI to ask permission to distribute my OpenGL-like +graphics library on the internet. SGI was generally receptive to the +idea and after negotiations with SGI's legal department, I get permission +to release it. +

+ +

+February 1995: Mesa 1.0 is released on the internet. I expected that +a few people would be interested in it, but not thousands. +I was soon receiving patches, new features and thank-you notes on a +daily basis. That encouraged me to continue working on Mesa. The +name Mesa just popped into my head one day. SGI had asked me not to use +the terms "Open" or "GL" in the project name and I didn't +want to make up a new acronym. Later, I heard of the Mesa programming +language and the Mesa spreadsheet for NeXTStep. +

+ +

+In the early days, OpenGL wasn't available on too many systems. +It even took a while for SGI to support it across their product line. +Mesa filled a big hole during that time. +For a lot of people, Mesa was their first introduction to OpenGL. +I think SGI recognized that Mesa actually helped to promote +the OpenGL API, so they didn't feel threatened by the project. +

+ + +

+1995-1996: I continue working on Mesa both during my spare time and during +my work hours at the Space Science and Engineering Center at the University +of Wisconsin in Madison. My supervisor, Bill Hibbard, lets me do this because +Mesa is now being using for the Vis5D project. +

+October 1996: Mesa 2.0 is released. It implementes the OpenGL 1.1 specification. +

+ +

+March 1997: Mesa 2.2 is released. It supports the new 3dfx Voodoo graphics +card via the Glide library. It's the first really popular hardware OpenGL +implementation for Linux. +

+ +

+September 1998: Mesa 3.0 is released. It's the first publicly-available +implementation of the OpenGL 1.2 API. +

+ +

+March 1999: I attend my first OpenGL ARB meeting. I contribute to the +development of several official OpenGL extensions over the years. +

+ +

+September 1999: I'm hired by Precision Insight, Inc. Mesa is a key +component of 3D hardware acceleration in the new DRI project for XFree86. +Drivers for 3dfx, 3dLabs, Intel, Matrox and ATI hardware soon follow. +

+ +

+October 2001: Mesa 4.0 is released. +It implements the OpenGL 1.3 specification. +

+ + +

+November 2001: I cofound +Tungsten Graphics, Inc. with Keith Whitwell, Jens Owen, David Dawes and +Frank LaMonica. +I continue to develop Mesa as part of my resposibilities with Tungsten +Graphics and as a spare-time project. +

+ +

+November 2002: Mesa 5.0 is released. +It implements the OpenGL 1.4 specification. +

+ +

+Ongoing: Mesa is used as the core of many hardware OpenGL drivers for XFree86 +within the +DRI project. +I continue to enhance Mesa with new extensions and features. +

+ + + +

May 1999 - John Carmack of id Software, Inc. has made a donation of
+US$10,000 to the Mesa project to support its continuing development.
+Mesa is a free implementation of the OpenGL 3D graphics library and id's
+newest game, Quake 3 Arena, will use Mesa as the 3D renderer on Linux.
+
+The donation will go to Keith Whitwell, who has been optimizing Mesa to
+improve performance on 3d hardware.  Thanks to Keith's work, many
+applications using Mesa 3.1 will see a dramatic performance increase
+over Mesa 3.0.  The donation will allow Keith to continue working on
+Mesa full time for some time to come.
+
+For more information about Mesa see www.mesa3d.org.  For more

Off-screen Rendering

+ + +

+Mesa 1.2.4 introduced off-screen rendering, a facility for generating +3-D imagery without having to open a window on your display. Mesa's +simple off-screen rendering interface is completely operating system +and window system independent so programs which use off-screen +rendering should be very portable. This feature effectively +enables you to use Mesa as an off-line, batch-oriented renderer. +

+

+The "OSMesa" API provides 3 functions for making off-screen +renderings: OSMesaCreateContext(), OSMesaMakeCurrent(), and +OSMesaDestroyContext(). See the Mesa/include/GL/osmesa.h header for +more information. See the demos/osdemo.c file for an example program. +There is no facility for writing images to files. That's up to you. +

+

+If you want to generate large images (larger than 1280x1024) you'll +have to edit the src/config.h file to change MAX_WIDTH and MAX_HEIGHT +then recompile Mesa. Image size should only be limited by available +memory. +

+ + +

Deep color channels

+ For some applications 8-bit color channels don't have sufficient + accuracy (film and IBR, for example). If you're in this situation + you'll be happy to know that Mesa supports 16-bit and 32-bit color + channels through the OSMesa interface. When using 16-bit channels, + channels are GLushorts and pixels occupy 8 bytes. When using 32-bit + channels, channels are GLfloats and pixels occupy 16 bytes. +

+

+ To build Mesa/OSMesa with 16-bit color channels: +

+      cd Mesa-4.x/src
+      make -f Makefile.X11 clean
+      make -f Makefile.OSMesa16 linux-osmesa16
+
+ + For 32-bit channels: +
+      cd Mesa-4.x/src
+      make -f Makefile.X11 clean
+      make -f Makefile.OSMesa16 linux-osmesa32
+
+ +

+If you're not using Linux, you can easily edit Make-config and add +an appropriate configuration. +

+

+The Mesa/tests/osdemo16.c file (available via CVS) demonstrates how +to use this feature. +

+

+BE WARNED: 16 and 32-bit channel support has not been exhaustively +tested and there may be some bugs. However, a number of people have +been using this feature successfully so it can't be too broken. +

Performance Tips

+ +

+Performance tips for software rendering: +

+
    + +
  1. Turn off smooth shading when you don't need it (glShadeModel) +
  2. Turn off depth buffering when you don't need it. +
  3. Turn off dithering when not needed. +
  4. Use double buffering as it's often faster than single buffering +
  5. Compile in the X Shared Memory extension option if it's supported + on your system by adding -DSHM to CFLAGS and -lXext to XLIBS for + your system in the Make-config file. +
  6. Recompile Mesa with more optimization if possible. +
  7. Try to maximize the amount of drawing done between glBegin/glEnd pairs. +
  8. Use the MESA_BACK_BUFFER variable to find best performance in double + buffered mode. (X users only) +
  9. Optimized polygon rasterizers are employed when: + rendering into back buffer which is an XImage + RGB mode, not grayscale, not monochrome + depth buffering is GL_LESS, or disabled + flat or smooth shading + dithered or non-dithered + no other rasterization operations enabled (blending, stencil, etc) +
  10. Optimized line drawing is employed when: + rendering into back buffer which is an XImage + RGB mode, not grayscale, not monochrome + depth buffering is GL_LESS or disabled + flat shading + dithered or non-dithered + no other rasterization operations enabled (blending, stencil, etc) +
  11. Textured polygons are fastest when: + using a 3-component (RGB), 2-D texture + minification and magnification filters are GL_NEAREST + texture coordinate wrap modes for S and T are GL_REPEAT + GL_DECAL environment mode + glHint( GL_PERSPECTIVE_CORRECTION_HINT, GL_FASTEST ) + depth buffering is GL_LESS or disabled +
  12. Lighting is fastest when: + Two-sided lighting is disabled + GL_LIGHT_MODEL_LOCAL_VIEWER is false + GL_COLOR_MATERIAL is disabled + No spot lights are used (all GL_SPOT_CUTOFFs are 180.0) + No local lights are used (all position W's are 0.0) + All material and light coefficients are >= zero +
  13. XFree86 users: if you want to use 24-bit color try starting your + X server in 32-bit per pixel mode for better performance. That is, + start your X server with + startx -- -bpp 32 + instead of + startx -- -bpp 24 +
  14. Try disabling dithering with the MESA_NO_DITHER environment variable. + If this env var is defined Mesa will disable dithering and the + command glEnable(GL_DITHER) will be ignored. +

Supported Systems and Drivers

+ +

+Mesa was originally designed for Unix/X11 systems and is still best +supported on those systems. All you need is an ANSI C compiler and the +X development environment to use Mesa. +

+ +

Others have contributed drivers +for the Amiga, Apple Macintosh, BeOS, NeXT, OS/2, MS-DOS, VMS, Windows +9x/NT, and Direct3D. +

+ +

+The following files describe the details for various platforms. +Be warned, some of these files (and drivers) may be very out of date. +

+ + + + +

+The standard Mesa distribution only supports software-based rendering, with +the exception of the 3Dfx Glide driver. +Information about other hardware support follows. +

+ + + +

+Note: +If you have NVIDIA hardware in your computer, +you should download and install NVIDIA's OpenGL library. You may +however, want to download Mesa in order to use its GLU and GLUT +libraries, or assorted demo programs.
